Beschreibungdescription
Meßgerät für die Stärke von Geweben zur Anwendung vorzugsweise in der Chirurgie, das insbesondere mit einem chirurgischen Heftgerät zur Bestimmung der Größe der zu verwendenden Heftklammern und des richtigen Abstandes, auf den das Gerät eingestellt ;werden sollte.Measuring device for the thickness of tissues for use, preferably in surgery, which is in particular with a surgical stapling device for determining the size of the staples to be used and the correct distance to which the device is set ; should be.
Die Chirugen verwenden neuerdings zunehmend Heftklammern statt konventionelle Nähte beim Verbinden vieler innerer Organe, angefangen vom Hiatus oesophageus bis zum Rektum. Dieser Trend geht im wesentlichen auf die Tatsache zurück, daß die Verwendung von Heftklammern viel leichter ist und eine große Anzahl schwieriger Verfahren durch die Verwendung von Heftklammern viel einfacher wird. Vielleicht von noch größerer Wichtigkeit ist jedoch der Umstand, daß die Verwendung von Heftklamnern ein sehr viel schnelleres Verfahren erlaubt und die zum Nähen erforderliche Zeit wesentlich reduziert und damit die Zeitspanne, während der der Patient unter Narkose gehalten werden muß, wesentlich reduziert.Surgeons have recently started to use staples rather than conventional sutures to join many internal organs, starting from the hiatus esophagus to the rectum. This trend essentially goes to the Back to the fact that the use of staples is much easier and a large number of difficult procedures becomes much easier with the use of staples. Perhaps of even greater importance however, the fact is that the use of staples allows a much faster process and significantly reduces the time required to sew, and therefore the length of time that the patient is under Anesthesia has to be kept, significantly reduced.
Die vorstehend erwähnten Vorteile chirurgischer Heftverfahren sind jedoch auch mit gewissen Problemen behaftet. Beispielsweise ist es notwendig, die richtige Heftklammergröße für die Stärke des zu verbindenden Gewebes auszuwählen. Weiter ist es leicht möglich, daß selbst dann, wenn die richtige Heftklammergröße gewählt ist, die Heftung in dem Gewebe entweder zu fest oder zu locker wird. Wenn die chirurgische Heftung zu fest ausfällt, wird die Blutversorgung für den Heilungsprozeß unterbrochen und das Gewebe wird nekrotisch. Wenn andererseits die Heftklammern zu locker sitzen, kannHowever, the aforementioned advantages of surgical stapling methods also have certain problems. For example, it is necessary to use the correct size staple for the strength of the tissue to be joined to select. Furthermore, even if the correct staple size is selected, it is easily possible that the stitching becomes either too tight or too loose in the fabric. If the surgical staple is too tight, the blood supply for the healing process is interrupted and the tissue becomes necrotic. If on the other hand the staples may be too loose

Hämorrhagie und/oder Verlust auftreten. Daher führen zu fest oder zu locker sitzende Heftklammern zu schwerwiegenden Problemen und Komplikationen.Hemorrhage and / or loss may occur. Therefore, staples that are too tight or too loose lead to serious ones Problems and complications.
Genau diese, für chirurgisches Heften typischen Probleme, verlangen nach einem Meßinstrument für die Stärke der durch chirurgische Heftklammern zu verbindenden Gewebe. Chirurgische Heftklammern sind in verschiedenen Größen erhältlich. Viele chirurgische Heftgeräte sind mit Einrichtungen versehen, die die Einstellung des Spaltes zwischen der Patrone oder dem die Heftklammern enthaltenden Kopf und dem Amboß, gegen den die Heftklammern geformt werden, ermöglichen, wodurch der Umfang bestimmt wird, in dem die Heftklammern gestaucht werden. Wenn die Stärke des zu verbindenden Gewebes bekannt ist, können Heftklammern geeigneter Größe leicht gewählt und der erwähnte Spalt in richtiger Weise eingestellt werden.Exactly these problems typical of surgical stapling, call for a measuring instrument for the strength of the surgical staples to be joined Tissue. Surgical staples come in a variety of sizes. Many surgical staplers are provided with devices that allow the adjustment of the gap between the cartridge or that of the staples containing head and the anvil against which the staples are molded, allowing the circumference to be determined in which the staples are compressed. When the strength of the tissue to be joined is known is, staples of suitable size can be easily selected and the mentioned gap set properly will.
Die Eigenart lebenden Gewebes macht eine Messung häufig schwierig, und zwar wegen seiner weichen, elastischen und plastischen Konstitution. Man hat Untersuchungen ausgeführt, um den optimalen Heilungsdruck beispielsweise für intestinales Gewebe zu bestimmen. Der optimale Heilungsdruck schwankt mit den verschiedenen Gewebearten. Lungengewebe beispielsweise ist von intestinalem Gewebe sehr verschieden. Daher muß ein Gewebemeßgerät, das von der Erfindung geschaffen werden soll, so ausgelegt werden, daß es den optimalen Heilungsdruck während der Gewebemessung für die jeweils zu messende Gewebeart ausübt. Dies kann leicht geschehen mit dem erfindungsgemäßen Gewebemeßinstrument, und zwar je nach Gewebeart nach dem gleichen Grundgedanken.The nature of living tissue often makes measurement difficult because of its soft, elastic nature and plastic constitution. Studies have been carried out to find the optimal healing pressure, for example for intestinal tissue to be determined. The optimal healing pressure varies with the different types of tissue. Lung tissue, for example, is very different from intestinal tissue. Therefore a tissue measuring device must that is to be created by the invention should be designed so that it provides the optimal healing pressure during the tissue measurement for the type of tissue to be measured. This can easily be done with the inventive Tissue measuring instrument, depending on the type of tissue according to the same basic idea.

The other side of the handle 3 can be provided with an identical scale, not shown, so that the instrument during its use can be read from both sides. The scale 24 enables the doctor to quickly determine the diameter of a tubular body element to be stapled to determine what follows in detail results.
Es sind Untersuchungen darüber ausgeführt worden, den optimalen Heilungsdruck für genähtes intestinales Gewebe zu bestimmen. Dieser Druck beträgt etwa 8 g/mm2. Für die Anwendung des hier beschriebenen Stärkenmeßgeräts für Gewebe hat es sich bei der Messung von intestinalem Gewebe als gut herausgestellt, daß Meßgerät über einen Dickenbereich von 0-4 mm auszulegen. Man sieht aus Fig. 1 und 3, daß die Skalen 19 und 20 sich über diesen Bereich erstrecken. Die Blattfeder 14 entwickelt eine konstante Federspannung, die bewirkt, daß die Backenflächen 2a und 4a zwischen ihnen befindliche Gewebe bei einem Druck von 8 g/mm2 bei halbem Arbeitsbereich (d.h.Studies have been carried out to determine the optimal healing pressure for sutured intestinal tissue. This pressure is about 8 g / mm 2 . For the use of the thickness measuring device for tissue described here, it has been found to be good when measuring intestinal tissue that the measuring device is designed over a thickness range of 0-4 mm. It can be seen from FIGS. 1 and 3 that the scales 19 and 20 extend over this area. The leaf spring 14 develops a constant spring tension which causes the jaw surfaces 2a and 4a to remove tissues located between them at a pressure of 8 g / mm 2 at half the working range (ie
wenn die Flächen 2 nun auseinander stehen) messen, wobei für alle praktisch auftretenden Zwecke dieser gleiche Druck über den Arbeitsbereich von 0-4 nun ausgeübt wird. Die Backen 2 und 4 sind so gestaltet, daß ihre Oberflächen 2a und 4a beim halben Arbeitsbereich, d. h. wenn die Backen-Flächen 2 mm auseinander stehen, parallel liegen, um eine maximale Genauigkeit der Gewebestärkenmessung sicherzustellen. Das Instrument 1 kann aus jedem beliebigen, für ärztliche und klinische Verwendung geeigneten Material hergestellt sein (einschließlich Kunststoff, Metall und Kombinationen der beiden, o.dgl.) und kann im autoklaven, durch Ä'thylenoxid, Bestrahlung oder durch andere übliche Verfahren sterilisiert werden.when the surfaces 2 are now apart) measure, where for all practical purposes this same pressure is now exerted over the working range of 0-4 will. The jaws 2 and 4 are designed so that their surfaces 2a and 4a at half the working area, i.e. H. when the jaw surfaces are 2 mm apart, lie parallel to ensure maximum accuracy of the tissue thickness measurement to ensure. The instrument 1 can be of any desired type, for medical and clinical use suitable material (including plastic, metal and combinations of both, or the like) and can in the autoclave, by Ä'thylenoxid, Irradiation or sterilized by other conventional methods.
Fig. 6 ist eine der Fig. 4 ähnliche Teilansicht. Die in Fig. 6 dargestellte Ausführungsform unterscheidet sich von derjenigen aus Fig. 4 darin, daß die Backe (in Fig. 6 mit 2b bezeichnet) seitlich abgewinkelt ist. Man sieht, daß in dieser Ausführungsform die andere Backe in ähnlicher Weise gewinkelt sein wird. Das erfindungsgemäße Instrument, das mit solchen gewinkelten Backen ausgerüstet ist, empfiehlt sich zur Verwendung vor allem in unzugänglichen Gebieten, um ausreichende Sichtbarkeit sicherzustellen.FIG. 6 is a partial view similar to FIG. 4. The embodiment shown in Fig. 6 differs from that of Fig. 4 in that the jaw (designated in Fig. 6 with 2b) is angled laterally. Man sees that in this embodiment the other jaw will be angled in a similar manner. The inventive Instrument that is equipped with such angled jaws is recommended for use before especially in inaccessible areas to ensure sufficient visibility.
Das vorstehend beschriebene Instrument kann wie folgt benutzt werden. Der Arzt, der das Instrument 1 wie eine Zange ergreift, drückt die Handgriffe 3 und 5, wodurch sich die Backen 2 und 4 gegen die Wirkung der Vorspannungsfeder 14 öffnen. Zur Erläuterung wird das Instrument bei seiner Anwendung zur Messung der Gewebestärke eines intestinalen Lumens 25 gemäß Fig. 5 erläutert. Die Backen 2 und 4 liegen um das intestinale Lumen 25,The instrument described above can be used as follows. The doctor who uses the instrument 1 like a Pliers grabs, pushes the handles 3 and 5, causing the jaws 2 and 4 against the action of the bias spring 14 open. For illustration purposes, the instrument is used to measure tissue thickness an intestinal lumen 25 according to FIG. 5. The jaws 2 and 4 lie around the intestinal lumen 25,
15ÖQ50/Q46815ÖQ50 / Q468
wie dargestellt, und danach wird der auf die Handgriffe 3 und 5 des Instruments vom Arzt ausgeübte Druck weggenommen. Die Feder 14 läßt die Backenflächen 2a und 4a einen Druck auf das Lumen 25 von etwa 8 g/min^ ausüben. Da der Arzt nicht langer Druck auf die Handgriffe 3 und 5 ausübt, ist die direkte Stärke-Ablesung in Millimetern auf den Skalen 19 und 20 in Verbindung mit den Markierungslinien 22 und 23 vollkommen unabhängig vom Arzt. Die Anordnung der Skalen 19 und 20 ist so getroffen, daß die direkte Ablesung von beiden Seiten des Instruments oder von der Rückseite desselben möglich ist.as shown, and thereafter the pressure exerted on the handles 3 and 5 of the instrument by the doctor is released. The spring 14 causes the jaw surfaces 2a and 4a to exert a pressure on the lumen 25 of about 8 g / min ^. Since the doctor no longer presses the handles 3 and 5 is the direct thickness reading in millimeters on the scales 19 and 20 in conjunction with the Marking lines 22 and 23 completely independent of the doctor. The scales 19 and 20 are arranged in such a way that that direct reading is possible from both sides of the instrument or from the rear of the same.
Man sieht, daß bei dem in Pig. 5 dargestellten Verfahren eine doppelte Stärke des intestinalen Lumengewebes gemessen wird. Wenn zwei im wesentlichen identische Lumina miteinander durch ein chirurgisches Heftinstrument zu verbinden sind, kann diese Ablesung direkt verwendet werden und als die Summe der Gewebestärken der beiden zu verbindenden Lumina betrachtet werden. Wenn die beiden zu verbindenden Lumina unterschiedliche Gewebestärken haben, kann jedes Lumen auf die in Fig. 5 dargestellte Weise gemessen und die sich ergebende Ablesung durch 2 geteilt werden. Dadurch ergibt sich der Gewebestärkenmeßwert für jedes Lumen. Die resultierenden Stärkenmessungen werden dann addiert, um die richtige Heftklammerhöhe und den richtigen Spalt zwischen dem Heftinstrument mit Patrone bzw. dessen Kopf und dessen Amboß zu bestimmen. Falls erforderlich, kann eine einzige Gewebestärkenablesung direkt dadurch gewonnen werden, daß eine der Backen 2 oder 4 in das hohle innere des Lumens eingeführt wird.You can see that the one in Pig. 5, a double thickness of the intestinal luminal tissue is achieved is measured. When two substantially identical lumens are attached to each other by a surgical stapling instrument are to be connected, this reading can be used directly and as the sum of the tissue thicknesses of the both lumina to be connected are considered. When the two lumens to be connected have different tissue thicknesses each lumen can be measured in the manner illustrated in Figure 5 and the resulting reading divided by 2. This results in the tissue thickness measurement for each lumen. The resulting strength measurements are then added to get the correct one Staple height and the correct gap between the Stapling instrument with cartridge or its head and its Determine anvil. If necessary, a single tissue thickness reading can be obtained directly by that one of the jaws 2 or 4 is inserted into the hollow interior of the lumen.
Wie oben angegeben, kann das Instrument an beiden Seiten des Handgriffs 3 mit einer Skala 24 versehen werden.As indicated above, the instrument can be provided with a scale 24 on both sides of the handle 3.
130050/046 0130050/046 0
Man sieht, daß eine identische Skala auch an beiden Seiten des Handgriffs 5 vorgesehen werden kann, je nach Bequemlichkeit. Um den Durchmesser des Lumens 25 zu messen, wird das in weichem Zustand befindliche Lumen längs der Oberfläche des Handgriffs 3 gelegt, wobei ein Rand an der O-Marke der Skala 24 liegt. Die Skala wird dann am anderen Rand des Lumens abgelesen. Die tatsächliche Messung ist in diesem Fall eine Messung etwa des halben ümfangs des Lumens, der proportional zum Lumendurchmesser ist. Die auf der Skala 24 aufgeführten Zahlen zeigen die verschiedenen reisförmigen Patronen oder Kopfdurchmesser, die zur Verwendung für das intralumenale Anastomose-Heftinstrument zur Verfügung stehen, da die Patrone oder der Kopf während des Verfahrens in einem der zu verbindenden Lumina lokalisiert ist. Dieses Verfahren macht die Wahl der richtigen Heftpatrone oder Kopfgröße zu einer einfachen Angelegenheit, wobei jedes Abschätzen entfällt.It can be seen that an identical scale can also be provided on both sides of the handle 5, depending on the convenience. In order to measure the diameter of the lumen 25, the lumen in a soft state is used placed along the surface of the handle 3, one edge being at the O-mark of the scale 24. The scale will then read from the other edge of the lumen. The actual measurement in this case is a measurement of about the half the circumference of the lumen, which is proportional to the lumen diameter. The numbers listed on the 24 scale show the various rice-shaped cartridges or head diameters that can be used for the intralumenal Anastomosis stapler will be available since the cartridge or head is located in one of the lumens to be connected during the procedure. This Procedure makes choosing the correct staple cartridge or head size a simple matter, being there is no need to estimate.

Diese zweite Ausführungsform des vorstehend erläuterten Stärkenmeßinstruments und seine Handhabung gehen im ein-This second embodiment of the strength measuring instrument explained above and its handling go into
130050/0468130050/0468
im einzelnen noch aus Nachfolgendem hervor. Dazu wird zur Erläuterung das Instrument 26 bei seiner Anwendung zur Messung der Gewebestärke eines intestinalen Lumens erläutert. Man sieht, daß das Instrument auch leicht so ausgelegt werden kann, daß mit ihm andere Gewebearten gemessen werden können, indem eine geeignete Vorspannungsfeder 42 und eine geeignete Skala 47 vorgesehen werden. Wie bei der Ausführungsform gemäß Fig. 1-6 wird das Instrument 26 mit einem Arbeitsbereich von 0 bis 4 mm dargestellt. Die Feder 42 mit konstanter Vorspannung ist so gewählt und konfiguriert, daß die Backenflächen 27a und 33a einen Druck auf zwischen ihnen befindliches Gewebe von etwa 8 g/mm^ über diesen Arbeitsbereich ausüben. Dies wird durch Verwendung einer Spiralfeder erreicht, die eine sehr niedrige Federkonstante hat und die zur Entwicklung der richtigen Kraft bei einem Abstand zwischen den Backenflächen 27a und 33a von 2 mm vorbelastet ist. Daher bleibt diese Kraft für alle praktisch vorkommenden Zwecke über den gesamten 4 mm-Bereich des Instruments konstant.in detail from the following. This will be to explain the instrument 26 when it is used to measure the tissue thickness of an intestinal lumen explained. It can be seen that the instrument can also easily be designed to accommodate other types of tissue can be measured by providing a suitable bias spring 42 and a suitable scale 47 will. As in the embodiment according to FIGS. 1-6, the instrument 26 has a working range of zero up to 4 mm shown. The constant bias spring 42 is selected and configured so that the Cheek surfaces 27a and 33a exert a pressure on tissue located between them of about 8 g / mm ^ over them Exercise work area. This is achieved by using a coil spring which is a very low one Has the spring constant and is used to develop the correct force at a distance between the jaw surfaces 27a and 33a is preloaded by 2 mm. Hence this power remains for all practical purposes constant over the entire 4 mm area of the instrument.
Der Arzt ergreift das Instrument mit seinem Daumen auf dem Kolbenkopf 36 liegend, wobei sein Zeigefinger und Mittelfinger die lateralen Flansche 29 und 30 ergreifen. Durch Ausüben einer Kraft auf den Kolben 35 werden der Kolben und der Schenkel 34 der Backe 33 im Korpus 28 axial verschoben. Dies trennt die Backen 27 und 33 gegen die Kraft der Feder 42. Bei geöffneten Backen und 33 ist das Instrument auf dem intestinalen Lumen in der Nähe der gewählten Heftstelle plaziert. Durch Wegnehmen der Kraft auf den Kolben 35 wird das Instrument das intestinale Lumen ergreifen und an ihm angelegt bleiben. Dies zeigt Fig. 11, wo bei 52 das intestinale Lumen gemessen wird. Da die Kraft auf den Kolben 35 vomThe doctor grasps the instrument with his thumb lying on the piston head 36, with his index finger and Middle finger grasp the lateral flanges 29 and 30. By exerting a force on the piston 35 the piston and the leg 34 of the jaw 33 in the body 28 are axially displaced. This separates the jaws 27 and 33 against the force of the spring 42. With the jaws and 33 open, the instrument is on the intestinal lumen in placed near the selected stapling point. By removing the force on the piston 35, the instrument becomes that grasp intestinal lumen and remain attached to it. This is shown in Fig. 11, where at 52 the intestinal lumen is measured. Since the force on the piston 35 from
130060/0488130060/0488
Arzt während des Messens freigegeben wird, ist die Messung vom Arzt unabhängig. Wenn die Messung in der in Fig. 11 dargestellten Weise abgenommen wird, wird die doppelte Stärke des Lumengewebes gemessen. Wenn zwei im wesentlichen identische Lumina miteinander verheftet werden sollen, kann die Ablesung auf der Skala 47 direkt zur Bestimmung der richtigen Hefthöhe und des Heftgerät-Spaltes benutzt werden. "Wenn zwei unähnliche Lumina miteinander verbunden werden sollen, kann jedes in der in Fig. 11 gezeigten Weise gemessen werden, wobei das Ergebnis für jedes auf der Skala 47 dann durch 2 dividiert wird. Dies ergibt eine Gewebestärke-Ablesung für jedes Lumen, wobei dann die Ablesungen zur Bestimmung der Hefthöhe bzw. der Heftklammerhöhe und des Heftinstrument-Spaltes addiert werden. Falls erforderlich kann eine einzige Stärkenablesung dadurch erreicht werden, daß eine der Backen 27 oder 33 in das offene Ende des zu messenden Lumens eingeführt wird. Zum Erleichtern des Ablesens empfiehlt es sich, daß die Vergrößerungslinse 49 eine Vergrößerung von wenigstens dem Zweifachen besitzt.Doctor is released during the measurement, the measurement is independent of the doctor. If the measurement is in the in Fig. 11 is removed in the manner shown, twice the thickness of the lumen tissue is measured. If two in If substantially identical lumina are to be stapled together, the reading on the scale 47 can be done directly can be used to determine the correct stapling height and the stapler gap. "If two dissimilar Lumens are to be connected to each other, each can be measured in the manner shown in Fig. 11, wherein the result for each on scale 47 is then divided by 2. This gives a tissue thickness reading for each lumen, with the readings for determining the staple height or the staple height and the Stapler column can be added. A single strength reading can thereby be achieved if necessary be that one of the jaws 27 or 33 is inserted into the open end of the lumen to be measured. To make it easier of reading, it is recommended that the magnifying lens 49 have a magnification of at least that Owns twofold.
In der Ausführungsform der Erfindung gemäß Fig. 7-10 stehen die Backenflächen 27 und 33 stets parallel und können weiter auseinander gefahren werden als die Oberflächen 2 und 4 der Ausführungsform der Erfindung gemäß Fig. 1. Da die Backen 27 und 33 bezüglich des Instruments 26 verschoben werden, können sie leicht an intestinales Gewebe in Fällen mit beschränktem Zugang angesetzt werden.In the embodiment of the invention according to FIGS. 7-10, the jaw surfaces 27 and 33 are always parallel and can be moved further apart than the surfaces 2 and 4 according to the embodiment of the invention Fig. 1. Since the jaws 27 and 33 are displaced with respect to the instrument 26, they can easily be attached to the intestinal Tissue can be used in cases with restricted access.

Bei der in Fig. 1 dargestellten Ausführungsform der Erfindung ist diese Ablesung etwa die Hälfte des Umfangs des Lumens 52. Da jedoch der Umfang in direkter und gut bekannter Relation zum Durchmesser steht, kann die Skala 51 entsprechend beschriftet werden. Die Skala 51 kann in Millimeter bedeutenden Ziffern wie bei der Ausführungsform gemäß Fig. 1 beschriftet werden. Die Skala kann auch mit anderen Bezeichnungen versehen werden. Bei der in Fig. 12 dargestellten Ausführungsform ist die Skala mit Buchstaben des Alphabets versehen, von denen jeder sich auf eine verfügbare zylindrische Heftklammerpatrone oder einen Kopf eines speziellen Durchmessers bezieht.Scale 51 is shown in Fig. 12. The lumen, again designated 52, is laid out along the surfaces 43 in a soft state, one of its edges resting against the protruding shoulder 50. The location of the other edge of the Lumens on the scale 51 can be read directly on the scale. In the embodiment shown in FIG of the invention, this reading is about half the circumference of the lumen 52. However, as the circumference is in direct and well-known relation to the diameter, the scale 51 can be labeled accordingly. The scale 51 can be labeled in numerals significant in millimeters, as in the embodiment according to FIG. 1 will. The scale can also be given other names. In the case of the one shown in FIG Embodiment, the scale is provided with letters of the alphabet, each of which is available on one cylindrical staple cartridge or a head of a special diameter refers.
Natürlich liegt es im Rahmen der Erfindung, das Gewebestärken-Meßinstrument der Fig. 7-12 mit mehr als einer Skala 47 und mit mehr als einer Skala 51 zu versehen, die um die Peripherie des Korpus 28 verteilt angeordnet werden können. Dies würde eine direkte Ablesung der Gewebestärke und eines Durchmessers eines tubusförmigen Körperorgans bei mehr als einer Stellung des Instruments 26 erlauben.Of course, the tissue thickness measuring instrument is within the scope of the invention 7-12 to be provided with more than one scale 47 and with more than one scale 51, which can be arranged distributed around the periphery of the body 28. This would be a direct reading the tissue thickness and a diameter of a tubular body organ in more than one position of the instrument 26 allow.
Diese und ähnliche Abänderungen liegen ohne weiteres im Rahmen der Erfindung.These and similar modifications are well within the scope of the invention.
